Studies in multiple species, including in post-mortem human tissue, have shown that normal
aging and/or acoustic overexposure can lead to a significant loss of afferent synapses …

Objectives: Endolymphatic hydrops (EH), a hallmark of Meniere disease, is an inner-ear
disorder where the membranes bounding the scala media are distended outward due to an …

Otoacoustic emissions (OAEs) provide information about the function of the outer hair cells
of the cochlea. In high-income countries, infants undergo OAE tests as part of the screening …

In a previous study, we observed:(i) significant hearing function impairment, assessed with
pure tone audiometry and distortion product otoacoustic emissions, in patients with …

For evoked otoacoustic emissions (OAEs), the stimulus and emission signals traverse the
middle ear (ME) in forward and reverse directions, respectively. In this study, a fully coupled …

Otoacoustic emissions (OAEs) arise from one (or a combination) of two basic generation
mechanisms in the cochlea: nonlinear distortion and linear reflection. As a result of having …

Several studies have suggested that distortion product otoacoustic emissions (DPOAEs)
may be an early marker not only of hearing loss (HL) but also of tinnitus. The purpose of this …

This paper proposes an alternative approach to acoustic Thévenin calibration of an ear
probe. An existing methodology derives the Thévenin-equivalent source parameters from …

Several types of otoacoustic emissions have been characterized in newborns to study the
maturational status of the cochlea at birth and to develop effective tests of hearing. The …

Animal models suggest that cochlear afferent nerve endings may be more vulnerable than
sensory hair cells to damage from acoustic overexposure and aging. Because neural …
